T=1300;//Temperature in K
R=8.314;//gas constant in J K^-1 mol^-1
p1=1.067*(10^5);//ratio of pressure of CO/CO2 for 1st reaction
p2=1.835*(10^5);//ratio of pressure of CO/CO2 for 2nd reaction
//To determine the values of delGo for required reaction
Kp1=p1^2;//equillibrium constant for the 1st reaction
